Valve for liquid fuel burners



June 9, 1936.- A. A. HALTER VALVE FOR LIQUID FUEL BURNERS Filed NOV. 14, 1955 lll/l Patented June 9, 1936 UNITED STATES PATENT OFFICE 1 Claim.

particularly designed to burn gasoline or coal oil.

It is aimed to provide a novel construction minimizing the danger of explosion and which operates automatically to cut 01T the supply of the fuel in the event of flooding or undue feed thereof.

A further object is to provide a construction wherein a float means operates automatically to attain the end mentioned.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.'

In said drawing:-

Figure 1 is a view in elevation illustrating the improved burner; and

Figure 2 is a vertical sectional view, on an enlarged scale, taken through the improved burner.

Referring specifically to the drawing, a burner as an entirety is designated Ill, preferably being annular and having inner and outer, upwardly flaring walls and l2, respectively, joined by `a base wall I3. Such walls provide a chamber I4 which contains a conventional annular wick I5, a conventional chimney therefor being shown at I6.

Surrounded by the burner and suitably supported within the same is a fuel control chamber or tank which is supplied with fuel, such as gasoline or coal oil from a tank I3, arranged at such a level that the liquid fuel will flow by gravity therefrom through pipes I9 into the interior of the tank or chamber Il, a fuel pipe joint being provided at where such pipe I9 passes into the chamber I'l.

Coacting with the outlet end of the pipe I9 is a needle valve 2| which is slidably mounted in a tube 22 forming part of a bracket 23 fastened within the chamber I1. A bracket 24 suitably supported within said chamber 23 has an This invention relates to a liquid fuel burner,

L-shaped lever 25 pivoted thereto as at 26 and at one end of which it is' connected by a pin and elongated slot 21, pivotally and slidably joining the valve 2|. The other end of said lever 25 carries a float 28 which is controlled by the fuel within the chamber and which is normally adapted to be maintained at substantially the level suggested by dotted lines in Figure 2. The f uel from chamber I1 passes through a pipe 29 to the base of the chamber I4, so that it may be retained by the Wick I5 through capillary attraction.

The parts are so constructed and arranged that the fuel at the normal level in the chamber and the base I4, the needle valve 2| will be open so as to afford a continuous supply. However, in the event of an undue rise in fuel, extinction of the flame or the like, the float 28 will be raised by the fuel level, thus rocking lever 25 and pushing the valve 2| against its seat at the end of pipe I9 and thus cutting off the supply of fuel.

Various changes may be resorted to provided they fall within the Spirit and scope of the invention.

I claim as my invention:-

A device of the class described having a charnber, a supply pipe rising from the bottom wall of the chamber and terminating in a horizontal outlet portion constituting a valve seat at its free end, a bracket depending from the top wall of the chamber having a sleeve aligned with and spaced from the outlet of said portion, a valve slidably disposed in said sleeve extending into said space and adapted to seat directly on the said free end of said portion, a bracket within the chamber, a float, said float having an upwardly extending arm pivoted to the second mentioned bracket below said valve, and being also pivotally connected to said valve on the opposite side of the sleeve to said portion.
